Switch Online NES games can't be played entirely offline

Going somewhere without internet? You may not be able to play installed Switch Online NES games.

Switch Online's batch of free NES games have optional online play for co-op and competitive action, but they can still be played offline. The $20 a year service grants access to a growing library of old-school NES games--this move actually replaces traditional Virtual Console on the Switch. There's a catch though: the retro classics will require subscribers to connect to the internet once a week in order to play.

"Nintendo Entertainment System - Nintendo Switch Online can by played for up to seven days without an internet connection," reads a FAQ page. "If you are unable to launch Nintendo Entertainment System - Nintendo Switch Online, then please try connecting to the internet again."
